Hello,

  I'm very new to d. I'm testing lazy evaluation and it seems like
  I've found bug w/ dmd  compiler on linux. Here are the details.



-- foo.d ---

import std.stdio;
import std.stdarg;
import std.string, std.conv, std.stream;
void foo(lazy void expression, ...)
{
   //expression();
   if (_arguments.length > 0) {
     _arguments[0].print();
     //writefln("got vararg:" ~ _arguments[0].name);
     if ((_arguments[0]) == typeid(char[])) {
       writefln("got vararg:" ~ std.conv.toString(_arguments.length));
       char[] tmp_msg = va_arg!(char[])(_argptr);
       writefln("GOOTT vararg: " ~ tmp_msg);

     }
   }
}

int main(char[][] args)
{
   foo(writefln("barz"),"foo");
   return(0);
}

--- foo.d ----

./foo
char[]
got vararg:1
